Please I need help I’m stuck

this is tricky b/c they are making the two triangles of different scales but of the same angles.... soooo  one is just a bigger copy of the other....

Step-by-step explanation:

Since this is a relation of the two side of each.. we can say the following...

=     where X = side  LA    soooo       solve for X  

 x *   = 4   (move the X , to the other side of the '=' sign

x = 4 *   ( yes.. we want to invert the fraction to move it to the other side )

x =

x = 6

so side LA is 6    :)

hope this !

asnwer is (g o h o f)(x) = 2x - 6/x + 7

step-by-step explanation:

given,

f(x) = x - 3/x

g(x) = x + 3

h(x) = 2x + 1

we need to find : (g o h o f)(x)

we can write (g o h o f)(x) = g[ h{ f(x) } ]

so first we find h{f(x)}

h{f(x)} = f(x) + 3 = (x - 3/x) + 3

h{f(x)} = x - 3/x + 3

now we find g[ h{ f(x) } ].

g[ h{ f(x) } ] = g(x - 3/x + 3)       {plug h{f(x)} = x - 3/x + 3 in g[h{f(x)}] }

g(x - 3/x + 3) = 2 (x - 3/x + 3) + 1

                    = 2x - 6/x + 6 + 1

                    = 2x - 6/x + 7

hence we get (g o h o f)(x) = 2x - 6/x + 7
